Maple Syrup Sunday is this weekend, and if the weather doesn’t warm up soon it could be a letdown because the cold temperatures are having a chilling effect on sap.Click here to watch the reportMore than 700 trees are tapped at Chase Farms in Wells. The syrup might be flowing, but it’s nothing compared to years past, said Rick Chase, who owns Chase Farms.“This time of year, it’s all of the business,” Chase said.Chase Farms has been around since the early 1700s, but this is the first time they’re taking part in Maine Maple Weekend.Click here for photos“We’re going to open for the season Saturday, so basically that’s what it’s all about is maple right now,” Chase said.The problem is, with such cold days and nights, the sap is staying inside the trees and that’s affecting production across the state.“You don’t normally see it so cold as long into the spring or as cold at night as it’s getting, which is the biggest problem,” Chase said.People at the Maine Department of Agriculture and the Maine Maple Syrup Producers Association said the icy temperatures have been a real issue, making supply tight in a few places.As long as it doesn’t warm up too quickly, the weather could just delay the syrup-making process. A quick spring warm-up could mean less production across the board.No matter what the weather is like, Chase Farms will have plenty of activities for people to enjoy this weekend, Chase said.
